[0002] 3D glass mold refers to the mold used in the high-temperature molding process of 3D glass. However, in actual use, when the temperature of the mold exceeds 200°C, the oxidized particles and dust impurities introduced by the feed material can easily cause bumps and concave spots to appear on the glass surface.

[0003] At present, in the existing 3D glass molding technology, most of the feeding and unloading at room temperature are done by manually wiping with a dust-free cloth to remove the oxide particles and dust on the mold to ensure the cleanliness of the mold cavity. However, when the feeding and unloading temperature exceeds 200°C, the dust-free cloth is easy to melt and contaminate the mold cavity, which will increase the frequency of concave and convex points on the product surface. Therefore, an additional polishing process is usually required, which not only increases the complexity of preparation, but also significantly increases the manufacturing cost, thereby restricting the development of the 3D glass industry. In addition, manual wiping at high temperatures poses certain safety risks.
